Interpixel interference mitigation using differential coding in vehicular visible light communication based image sensor

This paper proposes the differential coding in visible light communication using image sensor. The transmitted frame is a result of comparing the current bitstream with previous bitstreams. The purpose of this scheme is limiting the number of white LED in one frame to mitigate the interpixel interference (IPI). The image sensor is used to take snap consecutive image frames. The simulation outcome shows that proposed scheme gains the BER performance.
